DragonFireGames it's referring to tables sooo solutions include using the cursed "data browser" to set it or using the inspect console orrrrrrrrrrr perhaps since you have access to my repl firefly can do the job as well.... though for me I'd say inspect console is the easiest
as for my theory for why it crashes probably because the way the constructor is being built.... if you didn't know every JS/TS has a __proto__ function attribute that i believe is called when initializing new data or creating one after parsing it, I've never done it before but if it's overwriting a core structure of a data type that is used it'll probably force an error, then again I haven't debugged it so it could be for various other reasons other than that, considering that most of it was written in TS it will complain a lot more if data types aren't handled with care
